WASH APPARATUS.

SPECIFICATION forming part of Letters Patent No. 755,477, dated March 22, 190% Application filed June 9, 1903. Serial No. 160,758. (No model.)

To rtZZ whom, it may concern: I

Be it known that I, GHARLEs FREDERIK VIL- HELM FLINT, a citizen of the Kingdom of Denmark, have invented certain new and useful Improvements in Wash Apparatus, of which the following is a specification.

The present invention is an improved wash apparatus for water-closets, lavatories, &c., characterized by requiring no pressure by elevation, so that it may be put up in level with or even below the level of the receiver in which the rinsing has to be done. This is often of importance where the room employed has only a small height.

The principle of the improvement is that the water in an air-chamber is kept under pressure and the movement of the water is caused by expansion of the air confined over the water and not by the effect of the gravity, which will only in a small degree come into play when the wash apparatus is placed above the level of the receiver to be washed out. If this is not the case, the gravity will be without influence.

A way of executing the apparatus is shown in the accompanying drawing.

A closed tank a is, with a pipe 6, connected with the valve-casing c, which again by the pipe (Z is connected with the closet or other place that is going to be washed out.

The pressure-water piping is closed at e.

The valve-casing has two partitions f and g and a stuffing-box it.

The lever 70, which is connected with a handle Z, turns on the bolt 2'. The lever it carries a sliding weight 7' and is connected with the valve-spindle n, which is sliding in its longitudinal direction. The valve-spindle carries two obturators 0 and p, which correspond with and fit into the partitions f and g. The spindle is also supplied with grooves q. From the obturator 19 goes a cylindric-turned pipe 0", which at first for some length is unbroken and then supplied with small holes 8. A wire net t serves as a sieve for the water.

The manner in which the wash apparatus works is as follows: When the apparatus is at rest, the lever in will stand in the dotted The obturator 0 will close the opening in the partition f. When the handle is pulled, the lever A: will move into the position shown by the lines fully inked in, the water flows through the cuttings 9 while the obturator p closes the opening in the partition g. The water mounts into the air-chamber a and compresses the air. hen the pressure has reached a certain height, the spindle n will move toward the right, as the pressure works on a plane like the traverse section of the pipe 1'. The lever 71: is turned and gets into the position m, by which the apertures 8 go through the hole at g. The water now runs from the air-chamber a through the pipe 5, up through the inside of the pipe r and the apertures s and reaches, through the pipe d, the place to be washed out. In the meantime the conduit Z is barred at f. Through alterations in the proportions of the various parts (size of the air-chamber a, the traverse section of the pipe 9", the length of the arms of the lever lathe heaviness of the weigl1t 7',&c.) it is possible to obtain any pressure or any body of water required. It is of importance that the grooves g in the valve-spindle should be placed in such a manner as to allow of a gradual shutting ofl of the water in order to avoid jars in the conduit. The apertures 8 must only go through the hole at g when the weight j has passed the top position, while otherwise it might happen that only a partial opening would take place through the weight 7' not getting over the top position.

As may be seen, the tank a is empty when not in use, which is of great importance by the fact that the water through suificient isolation of the conduit 0 and the valve-casing c is prevented from freezing in the wash apparatus. Through the height of the pressure by which the water is made to flow out (in practice is used about 0.5 atmospheres) it is possible to attain a very strong Wash with a comparatively small quantity of Water. A

further advantage by the described wash apparatus is that a float-cock which might get out of order is not needed and it is always possible to get the same quantity of water into the air-chamber through the displacement of the weight 1' by which the pressure in the conduit is regulated. An overflow of the water is also out of the question and the apparatus works with hardly any noise. Instead of moving the lever is with a handle this may also be afiixed to a movable closetseat in such a manner that the lever is pulled when the seat rises after the use of the closet. Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a flushing device for Water-closets, an air-tight tank, pipe connections for placing said tank in communication with asource of supply of water under pressure and also the part to be flushed, valve devices for closing the communication with the part to be flushed and placing the reservoir in communication with the source of water-supply, said valve devices including means whereby when a certain amount of pressure issecured in the reservoir the valve devices are automatically reversed to cut oil" the water-supply and discharge the reservoir into the part to be flushed substantially as described.

2. In combination, a valve-casing having three branches, a pipe for supplying Water under pressure connected to one branch, an,

air tight reservoir connected to another branch, a pipe for leading to the part to be flushed from the third, a partition in said valve-casing having a large opening or valveseat therein, a valve-rod having a piston-valve fitting said opening and serving to open and close the same and having a second valve controlling the entrance of water to the reservoir, an operating-lever connected to said valverod,and a weight on said lever arranged to be overbalanced by the pressure of water on the piston-valve, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing Witnesses.
